Episode 256 – Empty Planet

The new Majin Buu charges towards the lookout, demanding Piccolo to produce Gotenks. Piccolo refuses, claiming that the promise was for two days, not one. He suggests Majin Buu could amuse himself by hunting down the remaining survivours while waiting for this fight. Majin Buu quickly rules out this possibility by unleashing millions of ki blasts, that destroy almost everyone on Earth. Piccolo tells Majin Buu that Gotenks can be ready within the hour, after Buu agrees, Goten and Trunks are rushed into the hyperbolic time chamber for final desperate training.
